wards otherpeopleunnecessarily. Eye prote-
ction is normally afforded by aversionrespon-
ses including the blink reflex.

^WARNING:
Looking directlyinto the beamwithopticalaids(e.g.
binoculars, telescopes) canbe hazardous.
Precautions:
Do not look directlyinto the beamwithopticalaids.
^CAUTION:
Looking into the laserbeam maybe hazardous tothe
eyes.
Precautions:
Do not look into the laserbeam. Make sure the laser is
aimed above or below eye level, (particularlywith fixed
installations, in machines,etc.)
Labelling
Start-up
Inserting/replacing batteries
1 Remove batterycompartment lidand attach
handstrap.
2 Insertbatteries,observingcorrectpolarity.
3 Close the battery compartment again.
Replace the batterieswhen the symbol 3
flashes permanently inthe display.
Only use alkaline or rechargeable
batteries.
Remove the batteries before any long
period of non-use to avoid the danger of
corrosion.
Changing the referencepoint
(multifunctionalendpiece)
The instrument canbe adapted for the following
measuringsituations:
• For measurements from an edge, fold outthe
positioning bracket until it first locks in place.
•For measurements from a corner,open the
positioning bracketuntil it locks in place,thenpush
the positioningbracket lightly tothe right to fold itout
fully.
A built-insensorautomaticallydetects the orientation
of the positioningbracket and adjusts the zeropoint of
the instrumentaccordingly.

Indirect measurement
The instrument can calculatedistances using
Pythagoras'theorem.
Make sure you adhere tothe prescribed
sequence of measurement:
• Al 1 targetpoints must beina horizontal or
verticalplane.
• The bestresults are achievedwhen the
instrument is rotated about a fixed point
(e.g. with the positioning bracket fully
folded outandthe instrumentplaced ona
wall).
• The minimum/maximumfunction canbe
used - see explanation in "Measuring ->
Minimum/maximum measurement". The minimum
value must be used for measurements atr ight angles
to the target; the maximum distance forall other
measurements.
sure that the first measurement and
the distance tobe measured areat right
angles. Usethe Minimum/maximum
function, as explained in "Measuring ->
